Paper Abstract

Based on the eigen equation and relationship among three normalized parameters, the approximate expression between the normalized standing parameter and the normalized frequency of TE01 mode of step index fiber is recommended. Then, the characteristics of TE01 mode field distribution is analyzed, the approximate expression between the radial coordinate for maximal amplitude of mode field and the normalized frequency is suggested. For the sake of clarifying the characteristics of diffraction far field of TE01 mode of step index fiber, its expression is given according to the scalar diffraction integral formula. Then, the approximate expression between the normalized spatial frequency for the maximal spatial frequency spectrum and the normalized frequency is suggested. Numerical calculations show that the relative error between approximate value and exact value are small than one percent within a large variable range and this indicate that these approximate expressions are relatively reasonable.
